@RequestMapping 未正确映射

我正在尝试设置一个控制器，但不幸的是无法查看输出...一切都正确渲染。当我去http://localhost:8080/CMT/content/edit我收到 404 页面。从 Netbeans 运行我的应用程序会转到http://localhost:8080/CMT

package com.cmt.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class Content {

    @RequestMapping(value="/content/edit", method=RequestMethod.GET)
    public ModelAndView edit(Model model) {
        ModelAndView mv = new ModelAndView();
        mv.setViewName("index");
        return mv;
    }
}

应用程序配置.xml

    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

我如何调试它并查看哪些有效，哪些无效？

Update

Netbeans 中的 GlassFish 服务器日志显示

Is your DispatcherServlet named app映射到/* in web.xml？从你的previous我看到的问题：

<servlet>
    <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/app-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
    <url-pattern>*.htm</url-pattern>
</servlet-mapping>

/content/edit网址不匹配*.htm图案。尝试/content/edit.htm寻找可能的解决方法。
